DNV-OSS-202 Verification for Compliance with UK Shelf Regulations

App.C: Prescriptive Requirements Established Practice

APPENDIX C
Prescriptive Requirements Established Practice

There are some areas where there are prescriptive requirements from the HSE OR ITEMS which are considered good practice, and are therefore expected to be complied with. Note this list is NOT exhaustive and reference should be made to the current legislation.

Lifeboat capacity

PFEER Reg.15 ACOP sets the standard that there is capacity onboard for 150% of the POB (personnel onboard).

Grab bags

PFEER Reg.18 ACOP requires that there are provided for each person smoke hooks, heat resistant gloves and a source of light.

In practice these are often grouped into a grab bag (where the heli-transit-suit is also stored) so that in case of an emergency you take one item with you. However, there is no requirement to put them in a "grab bag".

Emergency signals

PFEER Reg.11 (2) has specific details of how the alarm signals are to be. These are not the same as International Maritime Rules and Guidance, and need to be followed. NO exemptions can be given from these proscriptive requirements since the MODU owners tried to get this many years ago and were unsuccessful.

Temporary Refuge (TR) SCR Schedule 2

This is a place designed to provide a place where the personnel can safety muster and stay until such time as the OIM makes a decision about any incident and the need for abandonment. The TR needs therefore to be able to provide:

—	a safe place for muster
—	command and control facilities
—	communications
—	medical facilities
—	access to the means of escape and evacuation
—	breathable atmosphere for the POB for the duration that the TR is intended to be needed.

Others, however, come in through requirements which are set through other guidance and standard setting.

Lifeboat capacity (Info Sheet 12/2008)

The capacity of the lifeboats needs to be assessed on the basis of a weight per person of 98 kg, (and not the IMO value of 75 kg).

TR integrity (Information Sheet No 1/2006 (Revised and reissued January 2007)

This sets standards for the integrity of the TR and gives figures for the air change rate that is acceptable for a new TR area and an existing TR area.

ESDV

There are leakage rates that have been accepted for leakage of these valves, these are 1sm3/min gas or 6kg/min oil. This was previously in UK law SI 1029 which is now revoked.
